The Car Connection Expert Review

Marty Padgett Marty Padgett Editorial Director

The 2015 Audi A6 may look a little sedate, but it's a brilliant performer–thanks to its diesel-driven TDI, the supercharged A6, or turbocharged S6 versions.

For 2015, Audi’s A6 continues building its reputation for high-tech, if conservative, luxury. The A6 is a refined, civilized, smart, and capable sedan with the potential for a sporty side, too.

The A6 and performance-oriented S6 sedans are handsome vehicles, and we've commended Audi on its contoured sheetmetal and sleek designs in the past. However, even the A6 sits in the shadows of its mechanically similar, far less predictable A7 hatchback sibling. That car has been a top pick amongst our editors, while the A6 has received received more conventional scores with its more conventional design. The good news here is that the interiors are identical in both cars, and passengers will enjoy a mix of rich finishes, comfortable seating, and a long list of feature technologies.

With its swept-back, more rear-biased sport-sedan look, the A6's silhouette does rob some interior space. It feels somewhat smaller inside than some other mass-market cars in its size class, but front-seat space is excellent. Legroom can feel tight in back, and that middle space back there isn't adult-sized. That also makes the four-seat A7 and its practical hatchback cargo area, again seem more appealing. Trunk space is obviously smaller than in the A7 hatchback, but at 14.1 cubic feet it's even a bit small by luxury-sedan standards; the cargo floor is also quite high.

The A6 offers all the active-safety features you'll find on its luxury peers from Mercedes-Benz and BMW--including front and rear parking sensors, a rearview camera, blind-spot monitors, a night-vision system, and a head-up display. It's earned top five-star results from the federal government in crash-testing, as well as top 'good' ratings from the IIHS in all of the areas it's been tested (although not yet the tough small overlap test).

The 2015 Audi A6 and S6 are very well-equipped at the base level, as luxury sedans. But it's the options for the lineup that will really impress passengers. From Google Earth maps, to in-car wireless Internet access, to an innovative system that lets you trace out letters with your finger, this lineup goes above and beyond with tech options. The A6 also offers all the active-safety features you'll find on its luxury peers from Mercedes-Benz and BMW--including front and rear parking sensors, a top-view camera, blind-spot monitors, a night-vision system, and a head-up display.

The A6's base drivetrain pairs a 220-horsepower, 2.0-liter four with either a continuously variable transmission (CVT) and front-wheel drive, or an eight-speed automatic and quattro all-wheel drive. The four isn't slow, either; expect 0 to 60 mph times at about 7.5 seconds, up to a top speed of 130 mph. The CVT here does its best to pretend that it's a conventional automatic--and even offers a sport mode, paddle-shifters, and simulated ratios--but we'd take the eight-speed automatic and quattro with the 2.0T any day. And for pure efficiency, we'd choose the excellent A6 TDI, with a 240-hp turbodiesel six and an eight-speed automatic, a 0-60 mph time of about 5.5 seconds, and an EPA rating of 24/38 mpg, or 29 mpg combined.

In 2015, Volkswagen admitted diesel engines in this model illegally cheated federal tests and polluted beyond allowable limits. As part of unprecedented settlements with federal and state governments, Volkswagen agreed to buyback from owners diesel-equipped models of this vehicle. To determine eligibility for all affected Volkswagen, Porsche, and Audi models, Volkswagen set up VWDieselInfo.com for owners. (Owners of affected vehicles can enter their VIN numbers to see if their cars are eligible for buyback.)

Higher up on the performance scale are the supercharged six and turbocharged eights. The 310-horsepower supercharged V-6 that's offered in the A6 is paired with all-wheel drive and an eight-speed automatic transmission for a 0-60 mph time of 5.3 seconds. It's a flexible, fairly muted powerplant--but it's easily outstripped by the 420-horsepower turbocharged V-8 engine found in the S6. The S6's seven-speed S tronic gearbox and performance upgrades ensure excitement is just a tap-shift away--and that 60 mph is just 4.5 seconds away.

No matter which version you choose, the A6 has good handling, in either front- or all-wheel drive; even though its all-wheel drive system is biased to the rear it still prefers nose-heavy understeer. Models with Audi's Drive Select have better range and adaptability in their electric steering, throttle, transmission and even air-damper control, though steering feel isn't particularly a strength. The S6 has the tautest responses, of course; with impressively strong brakes and the firmest Sport settings, it's sweetly maneuverable in tight curves.
